Abstract

New compositions and methods of using those compositions as bonding compositions are provided. The compositions are preferably thermoplastic and comprise imides, amideimides, and/or amideimide-siloxanes (either in polymeric or oligomeric form) dispersed or dissolved in a solvent system, and can be used to bond an active wafer to a carrier wafer or substrate to assist in protecting the active wafer and its active sites during subsequent processing and handling. The compositions form bonding layers that are chemically and thermally resistant, but that can also be softened to allow the wafers to slide apart at the appropriate stage in the fabrication process.

RELATED APPLICATIONS

The present application claims the priority benefit of U.S. Provisional Patent Application Ser. No. 60/946,077, entitled HIGH-TEMPERATURE SPIN-ON BONDING COMPOSITIONS FOR TEMPORARY WAFER BONDING USING SLIDING APPROACH, filed Jun. 25, 2007, incorporated by reference herein

GOVERNMENT FUNDING

This invention was made with government support under contract number W911SR-05-C-0019 awarded by the United States Army Research, Development, and Engineering Command. The United States Government has certain rights in the invention.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention is broadly concerned with novel compositions and methods of using those compositions to form bonding compositions that can support active wafers on a carrier wafer or substrate during wafer thinning and other processing.

2. Description of the Prior Art

Wafer (substrate) thinning has been used to dissipate heat and aid in the electrical operation of the integrated circuits (IC). Thick substrates cause an increase in capacitance, requiring thicker transmission lines, and, in turn, a larger IC footprint. Substrate thinning increases impedance while capacitance decreases impedance, causing a reduction in transmission line thickness, and, in turn, a reduction in IC size. Thus, substrate thinning facilitates IC miniaturization.

Geometrical limitations are an additional incentive for substrate thinning. Via holes are etched on the backside of a substrate to facilitate frontside contacts. In order to construct a via using common dry-etch techniques, geometric restrictions apply. For substrate thicknesses of less than 100 μm, a via having a diameter of 30-70 μm is constructed using dry-etch methods that produce minimal post-etch residue within an acceptable time. For thick substrates, vias with larger diameters are needed. This requires longer dry-etch times and produces larger quantities of post-etch residue, thus significantly reducing throughput. Larger vias also require larger quantities of metallization, which is more costly. Therefore, for backside processing, thin substrates can be processed more quickly and at lower cost.

Thin substrates are also more easily cut and scribed into ICs. Thinner substrates have a smaller amount of material to penetrate and cut and therefore require less effort. No matter what method (sawing, scribe and break, or laser ablation) is used, ICs are easier to cut from thinner substrates. Most semiconductor wafers are thinned after frontside operations. For ease of handling, wafers are processed (i.e., frontside devices) at their normal full-size thicknesses, e.g., 600-700 μm. Once completed, they are thinned to thicknesses of 100-150 μm. In some cases (e.g., when hybrid substrates such as gallium arsenide (GaAs) are used for high-power devices) thicknesses may be taken down to 25 μm.

Mechanical substrate thinning is performed by bringing the wafer surface into contact with a hard and flat rotating horizontal platter that contains a liquid slurry. The slurry may contain abrasive media along with chemical etchants such as ammonia, fluoride, or combinations thereof. The abrasive provides “gross” substrate removal, i.e., thinning, while the etchant chemistry facilitates “polishing” at the submicron level. The wafer is maintained in contact with the media until an amount of substrate has been removed to achieve a targeted thickness.

For a wafer thickness of 300 μm or greater, the wafer is held in place with tooling that utilizes a vacuum chuck or some means of mechanical attachment. When wafer thickness is reduced to less than 300 μm, it becomes difficult or impossible to maintain control with regard to attachment and handling of the wafer during further thinning and processing. In some cases, mechanical devices may be made to attach and hold onto thinned wafers, however, they are subject to many problems, especially when processes may vary. For this reason, the wafers (“active” wafers) are mounted onto a separate rigid (carrier) substrate or wafer. This substrate becomes the holding platform for further thinning and post-thinning processing. Carrier substrates are composed of materials such as sapphire, quartz, certain glasses, and silicon, and usually exhibit a thickness of 1000 μm. Substrate choice will depend on how closely matched the coefficient of thermal expansion (CTE) is between each material.

One method that has been used to mount an active wafer to a carrier substrate comprises the use of a cured bonding composition. The major drawback with this approach is that the composition must be chemically removed, typically by dissolving in a solvent. This is very time-consuming, thus reducing throughput. Furthermore, the use of the solvent adds to the cost and complexity of the process, and it can be hazardous, depending upon the solvent required to dissolve the bonding composition.

Another method for mounting an active wafer to a carrier substrate is via a thermal release adhesive tape. This process has two major shortcomings. First, the tapes have limited thickness uniformity across the active wafer/carrier substrate interface, and this limited uniformity is often inadequate for ultra-thin wafer handling. Second, the thermal release adhesive softens at such low temperatures that the bonded wafer/carrier substrate stack cannot withstand many typical wafer processing steps that are carried out at higher temperatures.

There is a need for new compositions and methods of adhering an active wafer to a carrier substrate that can endure high processing temperatures and that allow for ready separation of the wafer and substrate at the appropriate stage of the process.

SUMMARY OF THE INVENTION

The present invention overcomes the problems of the prior art by broadly providing a wafer bonding method which includes providing a stack comprising first and second substrates bonded together via a bonding composition layer. The layer comprises a compound that can be oligomeric or polymeric, and that is selected from the group consisting of imide, amideimide, and amideimide-siloxane polymers and oligomers. The stack is subjected to a temperature sufficiently high to soften the bonding layer, and then the first and second substrates are separated.

The invention also provides an article comprising first and second substrates. The first substrate comprises a back surface and an active surface, and the active surface comprises at least one active site and a plurality of topographical features. The second substrate has a bonding surface, and there is a bonding layer bonded to the active surface and to the bonding surface. The bonding layer comprises oligomers and polymers, which are selected from the group consisting of imide, amideimide, and amideimide-siloxane polymers and oligomers.

In a further embodiment, the invention is concerned with a polymer or oligomer (or compositions comprising this polymer or oligomer dissolved or dispersed in a solvent system) having a formula selected from the group consisting of

where:

    • R5 is a cyclic aliphatic group (preferably C3 to C12, and more preferably C5 to C6); and
    • k is 0 to 20, preferably 0 to 10, and more preferably 0 to 5.

The composition should comprise at least about 30% by weight solvent system, preferably from about 50% to about 90% by weight solvent system, more preferably from about 60% to about 90% by weight solvent system, and even more preferably from about 70% to about 90% by weight solvent system, based upon the total weight of the composition taken as 100% by weight. The solvent system should have a boiling point of from about 100-250° C., and preferably from about 120-220° C.

Suitable solvents include those selected from the group consisting of N-methyl-2-pyrrolidone, xylene, dimethylacetamide, N,N-dimethylformamide, dimethyl sulfoxide, and mixtures thereof.

The total solids level in the composition should be at least about 10% by weight, preferably from about 10% to about 40% by weight, and more preferably from about 10% to about 30% by weight, based upon the total weight of the composition taken as 100% by weight.

In other embodiments, the composition could include a number of optional ingredients, including surfactants, adhesion promoting agents, plasticizers, and/or antioxidants.

When a surfactant is utilized, it is preferably present in the composition at a level of from about 0.1% to about 3% by weight, and more preferably from about 0.1% to about 1% by weight, based upon the total weight of the solids in the composition taken as 100% by weight. Examples of suitable surfactants include alcohol ethoxylates such as octyl phenol ethoxylate (sold wider the name Triton® X-100).

When an adhesion promoting agent is utilized, it is preferably present in the composition at a level of from about 0.1% to about 3% by weight, and preferably from about 0.1% to about 1% by weight, based upon the total weight of the solids in the composition taken as 100% by weight. Examples of suitable adhesion promoting agent include those selected from the group consisting of bis(trimethoxysilylethyl)benzene, aminopropyl tri(alkoxy silanes) (e.g., aminopropyl tri(methoxy silane), aminopropyl tri(ethoxy silanes), -phenyl aminopropyl tri(ethoxy silane)), and other silane coupling agents.

When an antioxidant is utilized, it is preferably present in the composition at a level of from about 0.01% to about 3% by weight, more preferably from about 0.01% to about 1.5% by weight, and even more preferably from about 0.01% to about 0.1% by weight, based upon the total weight of the solids in the composition taken as 100% by weight. Examples of suitable antioxidants include those selected from the group consisting of phenolic antioxidants (such as pentaerythritol tetrakis(3-(3,5-ditert-butyl-4-hydroxyphenyl)propionate sold under the name Irganox® 1010 by Ciba) and phosphite antioxidants (such as tris(2,4-ditert-butylphenyl)phosphite sold under the name Irgafos® 168 by Ciba).

The above ingredients can simply be mixed with the compound in the solvent system. The final composition should be thermoplastic (i.e., noncrosslinkable). Thus, the composition will be essentially free (less than about 0.1% by weight and preferably about 0% by weight) of crosslinking agents.

The melt viscosity of the final composition will preferably be less than about 200 Pa·S, more preferably less than about 100 Pa·S, and even more preferably from about 10 Pa·S to about 50 Pa·S. For purposes of these measurements, the melt viscosity is determined via rheological dynamic analysis (TA Instruments, AR-2000, two parallel-plate configuration where the plates have a diameter of 25 mm). Furthermore, this melt viscosity is determined at 300-350° C. and there is preferably less than about 3% by weight, and more preferably less than about 2% by weight, loss of the composition. In other words, very little to no thermal decomposition occurs in the composition at this temperature, as determined by thermogravimetric analysis (TGA).

Although the composition could be applied to either the carrier substrate or active wafer first, it is preferred that it be applied to the active wafer first. A preferred application method involves spin-coating the composition at spin speeds of from about 300-3,500 rpm (more preferably from about 500-1,500 rpm), at accelerations of from about 500-15,000 rpm/second, and for spin times of from about 30-300 seconds. It will be appreciated that the application steps can be varied to achieve a particular thickness.

After coating, the substrate can be baked (e.g., on a hot plate) to evaporate the solvents. Typical baking would be at temperatures of from about 80-275° C., and preferably from about 150-225° C. for a time period of from about 2-15 minutes, and more preferably from about 3-10 minutes. The film thickness (on top of the topography) after bake will typically be at least about 5 μm, and more preferably from about 5-50 μm.

After baking, the desired carrier wafer is contacted with, and pressed against, the layer of inventive composition. The carrier wafer is bonded to this inventive composition by heating at a temperature of from about 150-300° C., and preferably from about 180-300° C. This heating is preferably carried out under vacuum and for a time period of from about 1-10 minutes, under a bond force of from about 1 to about 15 kilonewtons.

FIG. 1( a) shows an exemplary stack 10 comprising active wafer 12 and carrier wafer or substrate 14. Active wafer 12 comprises a back surface 16 and an active surface 18. Active surface 18 can comprise one or more active sites (not shown) as well as a plurality of topographical features (raised features or lines as well as holes, trenches, or spaces) such as, for example, those designated as 20 a-d. Feature 20 d represents the “highest” feature on active surface 18. That is, the end portion or surface 21 is further from back surface 16 of wafer 12 than the respective end portions of any other topographical feature on wafer 12.

Typical active wafers 12 can include any microelectronic substrate. Examples of some possible active wafers 12 include those selected from the group consisting of microelectromechanical system (MEMS) devices, display devices, flexible substrates (e.g., cured epoxy substrates, roll-up substrates that can be used to form maps), compound semiconductors, low k dielectric layers, dielectric layers (e.g., silicon oxide, silicon nitride), ion implant layers, and substrates comprising silicon, aluminum, tungsten, tungsten silicide, gallium arsenide, germanium, tantalum, tantalum nitrite, SiGe, and mixtures of the foregoing.

Carrier substrate 14 has a bonding surface 22. Typical carrier substrates 14 comprise a material selected from the group consisting of sapphire, ceramic, glass, quartz, aluminum, silver, and silicon.

Wafer 12 and carrier substrate 14 are bonded together via bonding composition layer 24. Bonding layer 24 is formed of the polymer compositions described above, and has been applied and dried as also described above. As shown in the FIG. 1( a), bonding layer 24 is bonded to active surface 18 of wafer 12 as well as to bonding surface 22 of substrate 14. Unlike prior art tapes, bonding layer 24 is a uniform (chemically the same) material across its thickness. In other words, the entire bonding layer 24 is formed of the same composition.

It will be appreciated that, because bonding layer 24 can be applied to active surface 18 by spin-coating, the bonding composition flows into and over the various topographical features. Furthermore, the bonding layer 24 forms a uniform layer over the topography of active surface 18. To illustrate this point, FIG. 1 shows a plane designated by dashed line 26, at end portion 21 and substantially parallel to back surface 16. The distance from this plane to bonding surface 22 is represented by the thickness “T.” The thickness “T” will vary by less than about 8%, preferably by less than about 5%, more preferably by less than about 2%, and even more preferably by less than about 1% across the length of plane 26 and substrate 14.

The wafer package can then be subjected to subsequent thinning (or other processing) of the substrate as shown in FIG. 1( b), where 12′ presents the wafer 12 after thinning. It will be appreciated that the substrates can be thinned to thicknesses of less than about 100 μm, preferably less than about 50 μm, and more preferably less than about 25 μm. After thinning, typical backside processing, including photolithography, via etching, and metallization, may be performed.

Advantageously, the dried layers of the inventive compositions possess a number of highly desirable properties. For example, the layers will exhibit low outgassing for vacuum etch processes. That is, if a 15-μm thick film of the composition is baked at 200° C. for 2 minutes, the solvents will be driven from the composition so that subsequent baking at 200° C. for 60 minutes results in a film thickness change of less than about 5%, preferably less than about 2%, and even more preferably less than about 1% or even 0% (referred to as the “Film Shrinkage Test”). Thus, the dried layers can be heated to temperatures of up to about 190° C., preferably up to about 200° C., more preferably up to about 220° C., and even more preferably tip to about 240° C. without physical changes or chemical reactions occurring in the layer. For example, the layers will not soften below these temperatures. In some embodiments, the layers can also be exposed to polar solvents (e.g., PGME) at a temperature of 85° C. for 90 minutes without reacting.

The bond integrity of the dried layers can be maintained even upon exposure to an acid or base. That is, a dried layer of the composition having a thickness of about 15 μm can be submerged in an acidic media (e.g., concentrated sulfuric acid) or base (e.g., 30 wt. % KOH) at 85° C. for about 45 minutes while maintaining bond integrity. Bond integrity can be evaluated by using a glass carrier substrate and visually observing the bonding composition layer through the glass carrier substrate to check for bubbles, voids, etc. Also, bond integrity is maintained if the active wafer and carrier substrate cannot be separated by hand.

After the desired processing has occurred, the active wafer or substrate can be separated from the carrier substrate by heating to temperatures of at least about 200° C., preferably at least about 225° C., and more preferably from about 250° C. to about 350° C. These temperature ranges represent the preferred softening points of the bonding composition layer. This heating will cause the bonding composition layer to soften and form softened bonding composition layer 24′ as shown in FIG. 1( c), at which point the two substrates can be separated by sliding apart. FIG. 1( c) also shows an axis 28, which passes through both of wafer 12 and substrate 14, and the sliding forces would be applied in a direction generally transverse to axis 28. Alternatively, sliding may not be necessary, and instead wafer 12 or substrate 14 can be lifted upward (i.e., in a direction that is generally away from the other of wafer 12 or substrate 14) to separate the wafer 12 from the substrate 14.

It will be appreciated that separation can be accomplished by simply sliding and/or lifting one of wafer 12 or substrate 14 while maintaining the other in a substantially stationary position so as to resist the sliding or lifting force (e.g., by applying simultaneous opposing sliding forces to wafer 12 and substrate 14). This Carl all be accomplished via conventional equipment.

Any bonding composition remaining in the device areas can be easily removed using the original solvent that was part of the composition prior to drying as well as using solvents such as xylene, NMP, and dimethyl sulfoxide. Any composition remaining behind will be completely dissolved (at least about 98%, preferably at least about 99%, and more preferably about 100%) after 5-15 minutes of exposure to the solvent. It is also acceptable to remove any remaining bonding composition using a plasma etch, either alone or in combination with a solvent removal process. After this step, a clean, bonding composition-free wafer 12′ and carrier substrate 14 (not shown in their clean state) will remain.
